John's side-effect 2 was a surprise to everyone, including John himself. It started with a minor case of spontaneous combustion during a PowerPoint presentation, but quickly escalated into a full-blown existential crisis.
The room was filled with the smell of burnt coffee and the sound of sirens outside as John's presentation went up in flames, literally. The fire department arrived just in time to put out the flames, but not before John had a good laugh about it.
It was a side-effect that would go down in history as one of the most unpredictable and hilarious presentations ever given.
